I am facing network issues in Openstack. My openstack(MaaS + JuJu + Conjure-up) setup got deployed successfully but when i spin up an instance, there is no internet connectivity and my router is also not getting pinged from outside network(My Openstack VM can ping the router).

Do you have appropriate configured external network, route and nat enabled? Add this info in your question.

All configurations are properly , my router is SNAT enabled. External network is also resolvable , i am using the same network as the MaaS. I created a reserve range in MaaS and using this range as External network in Openstack.
